It's true that being collision-resistant is a strong enough property to make collisions unlikely, but it doesn't hold that collision resistance is a requirement for such a hash function.

What is the relevance of collision resistance in this case? Why do you say it's a primary requirement of a hash function here? Why isn't uniformity with a large enough image space enough? Given that there is no adversary trying to produce collisions of generated identifiers, why does it matter that collisions are hard to deliberately create, rather than simply unlikely to occur?
